UK supermarkets picked up a host of top medals at this year’s awards for their own-label wines, with Marks & Spencer’s Finest Reserve Port winning best in show for under £15.

Demand for Asda’s bargain bottle of red, usually priced at £5.75, crashed the supermarket’s online Wine Shop after a flurry of orders.

It was praised for flavours of "freshly crushed black fruit, creamy vanilla yoghurt and pepper spice" and noted for its good value.

Ed Betts, Wine Buying Manager at Asda, said the supermarket are “very proud” at picking up multiple prizes at this year’s awards.

“Our team of wine experts are always striving to offer our customers the very best value and our award for Best Single Varietal Red under £15 award in particular demonstrates this,” he said.

“At just £5.75, the exclusive La Moneda Reserva Malbec is the perfect example of how we're able to offer shoppers exceptional quality at low prices.

“The La Moneda Reserva Malbec is also currently on rollback at £4.37, and as the perfect match to barbecued meats, we're expecting high demand in the coming weeks!”
